Add the 1.6X Tele-Converter to the front of your HDR-FX1 lens to shift its focal range in the telephoto direction. The perfect tool when it"s inconvenient, dangerous, or even impossible to move as close to the subject as you"d like. The 1.6X Tele-Converter alters your zoom"s focal length range - with no appreciable light loss. Note vignetting occurs when zoomed to the wider angles.The Tele-Converter is specially effective in "run-and-gun" shooting situations because it attaches quickly to the front of the existing lens.
